X(cross) Development Systemmake AGL application development easier

December 2017X(cross) Development System 2

IoT.bzh● Located in France - Brittany

( Vannes / Lorient / Rennes )

● People background:– 40% coming from Tizen IVI (Intel+Samsung)– 40% coming from Wind River– 20% coming from industry

● Working on AGL since 2015● First technical contributor

on AGL

December 2017X(cross) Development System 3

Key Focuses● Cybersecurity

● Secure Application Framework (life cycle, MAC, Cynara, Systemd, Cgroups, Namespaces ...)

● Vehicle to Cloud, Identity management● Securing key platform services (audio, signaling, graphics …)

● Development Tools● Docker Platform development (AGL SDK)● Apps development from IDE: XDS (Cross Development System)● Platform Monitoring tools

● Integration● Yocto recipes, Releases automation & Testing (CI)● Renesas boards support

● Community Support● Documentation (kickstart, developer samples, guides …)● White Papers & Conferences (Genivi, AGL, Fosdem, ELC …)

December 2017X(cross) Development System 4

X(cross) Development System (XDS)● Dedicated to Applications Developers

enable apps developer without Yocto skills→● Cross-platform build using AGL SDK toolchain● Secure packaging (.wgt files including signatures)● Deploy on development boards (or Qemu image)● Remote debugging from IDE● Easy target access (console, SSH, …)● Developer environment is a standard IDE● Dashboard Web App to manage configurations and trigger actions

● Provide an XDS API ie CI workflows or specific environments→

December 2017X(cross) Development System 5

Key Features● Multi-platform : no dependencies on developer host

(Linux / Windows / MacOS)

● Easy to setupNear-zero install, no admin privileges required

● Application sources remain localCompatibility with existing IT policies (e.g. corporate backup, git, ...)

● Cross toolchain & tools embedded in a container :

● Local : run locally (local subsystem, virtual machine, docker container ...)

● On-premises : run on a local build server● Cloud : SaaS

● Leverage specific OS capabilities where applicable(e.g. Linux for Windows Subsystem, docker)

December 2017X(cross) Development System 6

Targeted Use CasesSingle Host mode

● Host: Windows

● IDE: Eclipse

● Container: Linux Subsystem

● Sources: shared through native access

Local Network mode

● Host: Linux

● IDE: Visual Code

● Container: Docker

● Sources: shared through docker volume

Cloud mode

● Host: Linux

● IDE: Eclipse

● Container: Docker running in the Cloud

● Sources: shared through sync tool

December 2017X(cross) Development System 8

XDS Implementation● Written in GO

(portable Linux/Windows/MacOS)● Dashboard (webapp Angular4, TypeScript 2) to make

development setup easier● REST API + WebSocket (socket.io)● File synchronization based on Syncthing [1] to support

Cloud model● XDS server integrated into AGL SDK docker image

(see flavour xds [2])

December 2017X(cross) Development System 9

XDS building blocks● xds-server

– Core of the system, running in container:● REST API interface over HTTP to config and trigger commands● Websocket to get asynchronously data (commands output) or events (commands

exit)● Control file synchronizer (Syncthing) on server/ in container ● Manage (install, list, remove) AGL SDKs

● xds-agent (client)– Client side part, running on developer host.

● Provide Dashboard as a webapp● Control file synchronizer (Syncthing) on developer's machine● Target terminal (work in progress)

● xds-cli– Command line tool for XDS.

● xds-gdb– Command line tool to allow application debugging (based on gdb).

December 2017X(cross) Development System 10

Develop AGL app with XDS1) Install xds-server on a build server machine

2) Install xds-agent and start-it on your machine

3) Browse XDS dashboard: http://localhost:8800

4) Add a new project

5) Cross build/compile your project using either :

1) Dashboard build page

2) IDE using xds-cli

6) Deploy app

7) Source debug from IDE (xds-gdb)

December 2017X(cross) Development System 11

Available as today● Release Candidate 1 (v1.0.0-rc1)

– Pre-build docker image including XDS server– Packaged Multi-platforms (Linux / Windows/ MacOS)

host tools : xds-agent, xds-cli, xds-gdb– Supported file sharing: Cloud mode or path

mapping – Command line tool (xds-cli) or Webapp (Dashboard)– IDE integration (manual setup)– Debugging mode (based on gdb and AGL app-

templates)
